Apple just filed a patent that could be the harbinger for its next generation product. Sure, the Apple Watch hasn't hit the market yet, but that doesn't mean that the company isn't already looking toward the future.
Its newest patent looks to be a stylus of some kind. Given Apple's innovative track record, I expect this pen to be more than your run-of-the-mill stylus.
According to the patent, the stylus would be packed with accelerometer sensors and transmitters that would enable it to connect to other devices.
How would this product be used? Well, that remains to be seen. But what you can see right now is the picture that came along with Apple's patent filing.
